Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Toxicity to aquatic algae and cyanobacteria

Description of key information
With high probability not harmful to aquatic algae, no toxic effects occur at the range of solubility.
Key value for chemical safety assessment
Additional information
In an algae study (exposure during 72 hours) no inhibition of algae growth, expressed as biomass and growth rate was observed at the highest concentration tested (30 mg/L, nominal) (Ciba-Geigy, 1992). The study was performed according to EU-guidelines. Analytical determinations revealed less than 10% of the nominal concentrations at the end of the test period. However, this is not as relevant since the measured concentration was still well above the water solubility of the test item. Thus no toxic effects occured within the range of water solubility.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
